Question

solve the question????

Answer 1

Step-by-step explanation:

let x = 3.8888..... ------> (1)

let 10x = 38.8888.... -----> (2)

equation (2) - (1)

10x = 3.88888....

(-) x = 0.38888....

........................................................

9x = 3.50000...

.........................................................

9x = 3.5

x = 3.5/9

x = 35/90

Answer 2

Step-by-step explanation:

let x = 3.888----- -1

multiply by 10 on both sides

10x = 38.888----- -2

subtract 1 from 2

10x-x = 38.888---- - 3.888---

9x = 35

x = 35/9
